Patent GB-663598-A (GB)
Abstract: 663,598. Sharpening knives. LIPTON, B. July 13, 1950 [Aug. 26, 1949], No. 22227/49. Class 60 A knife sharpener comprises a casing, adapted to stand firmly on a table, containing an electric motor that drives a horizontal spindle which carries a grinding or abrading wheel which is located at a slot or opening in the casing, the casing carrying on both sides of the wheel a guide plate so that the knife can be drawn first across one plate in contact with one side of the wheel and then across the other in contact with the other side of the wheel thereby sharpening both sides of the knife. The casing 1, Figs. 1 and 2, comprises a metal die casting and is cast with bosses 2 receiving screws for securing a base plate 3 which projects slightly beyond the contour of the casing to form a rib 4 entering a groove in a rubber strip 5 secured at its two ends to the base plate. The casing is cast with internal projections forming arched slots 6 which receive thin plates 7, 8 dividing the casing into three compartments. The middle compartment contains a series of plates 9, Fig. 4, of rectangular frame-like shape bolted together by bolts 10 which also pass through four vertical side strips 11, the lower ends of which are turned out to form flanges 12 secured by screws 13 to the base plate 3; suitable coils 14 around one limb 15 of the pack of plates 8 serve to produce a transformer, whilst the other limb 16 is bored horizontally to receive a rotor thereby constituting an electric motor. The rotor carries a horizontal spindle 18 projecting through the partition plate 7 into one end compartment where it carries the abrading wheel 19. The top of the casing above this end compartment is formed with a deep wide channel 20 which in front view is roughly V-shape; the sides of this channel in plan view are also at an angle to each other so as to approach near to the wheel at one side as shown at 21; at the other side 21<SP>1</SP> the plates are spaced further from the wheel, spring strips 22, 23 engaging the side of the groove to hold the knife in position, so that only the edge of the knife comes in contact with the wheel and the rest of the surface of the knife is clear of the wheel. The sides of the groove are covered with metal plates 24, 25. The casing above the middle compartment is formed with a grill 40 on one side for cooling purposes and the partition plate 8 at the end opposite to the abrading wheel is also formed with a grill. The motor spindle 18 on its opposite end carries a fan 27 within the middle compartment adjacent the other partition plate 8. The casing at this end does not carry the rubber strip and its lower edge has an opening 28 so that flex can pass into the casing. The casing is formed with a handle 29 adjacent which is a switch 30. The casing may be of hard plastic. In a modification, Fig. 5, the motor and fan are mounted in one end compartment 33, the middle compartment 34 being formed with the deep wide channel 20 through which the grinding wheel 19 projects. The casing at the other end compartment 35 forms the handle 29. A filter 31 is slidably mounted in the slot 6.

Title: Alarm device
IPC: G08B21/02
Filed: 1979-04-10
Abstract: An alarm device is desirable for persons subject to armed hold-up, which allows an alarm to be given in spite of the user being forced to remain immobile. The device consists of a link (3) for inclusion in a conventional waist-band or belt (1), which should be made of substantially non-extensible material. This link has a pair of contacts (4) which are urged by a spring (5) info an open-circuit position. To give the alarm, the wearer expands his waist-line by stomach-muscle operation, which closes the contacts (4) to operate an alarm transmitter (7). The transmitter is attached to the belt or otherwise concealed about the wearer. The strength of the spring (5) is adjustable by the wearer so as not to be susceptible to normal movements, but to respond only to deliberately induced over-expansion. <IMAGE>

Title: Load responsive brake control valves
IPC: B60T8/18
Filed: 1979-05-24
Abstract: A braking force regulator for motor vehicles has a housing 1 with a valve 8 housed in a piston 5 subject to the influence of the brake pressure and a control spring 16. For load-dependent regulation, an adjusting element 21, e.g. cam-operated, is provided which acts upon the valve element 11 of the valve 8. The adjusting element 21, the piston 5, the valve 8 and the compression spring 16 are axially aligned. The adjusting element 21 may be moved automatically into a central position in the event of a break in the linkage. The compression spring 16 may be adjustable as regards the initial stressing force or the spring rate. Adjustment is prevented during braking by the braking pressure producing a wedging action on balls or a ring 56 (Fig. 7). <IMAGE>
Patent GB-2025174-A (GB)
Title: Magnetic devices utilising garnet epitaxial materials
IPC: H01F10/24
Filed: 1979-06-27
Abstract: The application describes new magnetic materials for use in magnetic bubble devices. The materials are based on the prototype garnet (YIG) in which the dodecahedral site is substituted with lanthanum, samarium or europium and at least one of lutetium, ytterbium, thulium and yttrium. These mixed garnet compositions can be tailored to support very small bubbles, or to increase bubble mobility, or a desired combination of both. The new compositions are based on the recognition that lanthanum can be incorporated in the dodecahedral site to adjust the crystal lattice parameters while leaving the functional properties of the layer essentially unaltered. The substitution proportions are in the range 0.2 to 0.8 atoms per formula unit of lanthanum, 0.05 to 0.8 of samarium or europium and 0.5 to 2.5 for the last component.

Filed: 1980-08-08
Abstract: A walking beam conveyor for moving elongate objects in a conveying direction transverse to the lengths of the objects has at least one set of moving beams 12 which extend in the conveying direction but are transversely spaced apart. The beams execute a rotational movement in a vertical plane through the lengthwise axis. The displacement of objects on the conveyor in each rotational movement can be varied by providing a set of plates 14 fixed in the conveying direction but adjustable vertically so that the upper surfaces of the plates be at a selected level between the upper and lower extremities of the movement of the beams. The invention is especially applicable to a billet feeding and turnover bank. Preferably, two sets of moving beams 12, 13 displaced in phase are provided. <IMAGE>

Title: Photomultiplier tube
IPC: H01J43/20
Filed: 1980-10-30
Abstract: In a photomultiplier tube having a circular-cage type dynode arrangement, a first-stage curved dynode 31 comprises a first curved portion 32 closer to a photocathode 3 and a second curved portion 33 having a smaller radius of curvature than the first arc and smoothly joined to the first arc. With this arrangement secondary electrons from the first stage dynode can be directed onto the second stage dynode 12 and are less likely to be diverted to the fourth stage dynode 14 so that the anode current is more uniform for a given intensity of incident light over the range of positions at which light can impinge onto the photocathode. <IMAGE>
Patent GB-2089469-A (GB)
Title: Rotary Coupling System
IPC: F16D1/10
Filed: 1980-12-12
Abstract: Alignment of the splines (22a, 23a, 32a) of first and second coupling members (20, 30) is achieved (mostly) by progressive inter-engagement of sawtooth dogs (25a, 42c) respectively of the first coupling member (20) and of a third coupling member (40) splined to the second one (30). Upon inter-engagement of the sawtooth dogs (25a, 42c) the third coupling member (40) yields slidingly along the second one (30) against a spring (50) to enable the splines (22a, 23a, 32a) to inter-engage. Because of the liability (in certain known positions of the first and third coupling members (20, 40) of the sawtooth dogs (25a, 42c) to abut nose-to-nose without inter-engaging, the splines (22a, 23a, 32a) are made to be inter-engageable in these positions. <IMAGE>
